Summary: cPickling bug

Initial Comment:
I get a ClassCastException when the unpickler tried to
call __setstate__. It works fine with CPython (both
pickle and cPickle) and it works fie when I use pickle
in jython. But it fails using cPickle in Jython.

I was mainly leaving this open because test_cpickle still fails.  Moving
this out of 2.2beta since we're not focusing on library compatibility as
much.

Is there a test case for this?
import cPickle
a = cPickle()
i = 1000
x = a.dumps(i)
print x
v = a.loads(x)
print v

this works ok.  Also a class that defines __setstate__ works ok from what
I can see:
>>> class f:
...    def __setstate__(self, r):
...       print r
...
>>> g = f()
>>> x = a.dumps(g)
>>> x
'(i__main__\nf\np1\n(dp2\nb.'
>>> x2 = a.loads(x)
{}
>>> x2
<__main__.f instance 1>
>>>
